Math problem?

[TONY206]

I forgot this formula, I need to know the total of 11400 thirty X and each period is 3% more so..

11400
+
11742 (which is 11400+3%)
+
12094.26 (11742+35)

etc

You know what I'm talking about? It should be 400,000-425,000. Thanks

Wait...you want the summation of the total sum?

 

[TONY206]

Yes...

example: I get paid 11400, then I get paid 11742 (3% higher payment), then 12094.26 (3% more the previous) and I need to know the total paid to me.

26...yes it's 26

 

[TONY206]

Actually should be around 542,000 but I would like to know the exact amount if possible. Should be a pretty easy formula, I just forget how. Thanks

cant you put that in excel?

Do it by hand.

for real just write it out 30 times son!

google 'factorial' thats not a true factorial but its the same type of pattern and you can probably find it from there. might be easier to google 'n!' which is the generic formula for factorials.

 

[MEXCOM]

It's not a true factorial because it's not even a factorial at all. A factorial or N! given that N=4 would be the same as multiplying out 4*3*2*1. He doesn't want to multiply anything out he wants to add it up. Which is why you need a Summational formula. But like Kayvee said, work it out in Excel because otherwise you'd have to do it by hand and it'll take too long.

oh i see you counted them as final sum.

 

[TONY206]

Idk how you did it but you don't even have the 2nd number right.

Should be

A=start

A
A+3%=B
B+3%=C
C+3%=D
etc
Then add them all up.
